I can't put a match to your son's bike in a dark room. All I can say is use MM's or try your calculating again. Last ditch keep changing the bike untill he feel's comforatble not to WP's spec.
Ricky like's 120mm I like 96mm everyone like's certain thing's.

i thank you very much for the advice. well, i guess its time to buy a metric ruler.i am new to the forum, and have deviously gotten my two boys into dirtbikes.its been 23years since i had one. we now have a ktm65, honda 70, polaris 90, xr400. all brand new! i,m trying to get the ktm tuned for my 8yr old to get used to by spring. he will be racing at the moriartymx.com track. my wife and i figured that the first thing should be suspension. the first thing in suspension is sag. we can't get the sag set right using inches so we will try mm's. we want the bike to do its best for himand i was wondering if anyone knows of a book that deals with setup ? maybe it would be best to send the shock and fork to race tech or someone else?

The moderator Jeremy is a Susension expert and work's on all suspension and has info on every last bit. He can go into detail's. Welcome DRN is very helpful I hope you have a good time. when you set the sag to manufacture spec's that is to put you in the ballpark but your son will have to ride and ride untill he is comforatble on the bike. Eric has a book out. He has three book's out if I am right? Not sure if they deal with The 65SX.

If you're not able to set the sag using the english ruler, you're not going to have any better luck with a metric. If the preload nut can't be adjusted to get the proper sag, then your spring is too soft or hard.

i hope you have read my post. i am a father that is lucky to have 2 little boys. unfortunatly, that also means maintenance on at least 3 bikes.for a while. if you have some helpful info, book(s)i would greatly appreciate laerning more. why does a 2000 xr400 come with a shock that is too heavy for a 190lb rider?

Caster,
The Race Tech emulators work great! The shock spring is too stiff but a revalve would help out. At that age they grow FAST! The Emulators you can install and tune yourself.
